DETACHABLE RUBBER- HEEL.

Application filed April 5,

My invention relates to a new and useful improvement in detachable rubber heels, and has for its primary object. to provide a deviceof this character whichmay be readily and quicklyremovcd or replaced, thereby making it possible fora personto replace worn rubber heels with new ones, or change the rubber heels of apair of shoes, so that the wear will be more evenly disposed and thus increase the life of the rubber heels.

Another object ofmy invention is to pro: vide an exceedingly simple and effective attaching device for rubber heels which when secured upon the ordinary heel of a shoe will readily guide into .place a rubber heel made to coact therewith, and finally lock.

said rubber heel in position so that it may not he accidentally displaced; and astill' further object of my invention is to so construct the attaching device that it will offer a large bearing surface to that portion of the rubber heel which is located thereon-so as to avoid chafing or Wearing away of that portion of the rubber heel in contact. with the locking device, and provide for the entire concealment of the attaching device within the rubber heel, except the thin edge at the surface of the inner curved portion of said heel.

lVith these and other ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which:

Fig. 1, is a plan View of a rubber heel madedn accordance with my present invention.

Fig. 2, is an edge viewof Fig. 1 looking in the direction of the arrow adjacent to the latter.

Fig. 3, is a section on the line 3-3 of Fig. 1. I

Fig. 4:, is a detail perspective view of the attaching device.

In carrying out my invention as herein embodied, 11 represents a rubber heel made in accordance with my improvements, in which two L-shaped grooves 12 are formed longitudinally thereof, opening upon the innor surface of the heel and a locking groove 1927. Serial No. 18min.

1,3 which is here shown as semi-circular in shape.

lt represents the attaching device which is preferably made of sheet. metal haying the Lss ape flang s aced ad pted haras into the L-shaped grooves 12,.an'dalso hav ing a locking member 16, which latter is adapted to engage the groove 13. Thisattaching device has two or more holes ll' formed through the body thereof, through which nails or screws are driven forsecuring itto the ordinary heel of a shoe. Y The heel 11 also has an inclined surface 118, which surface isv below the general level, of the inner, surface of the heel to facilitate the attaching of the rubber heel to the attaching device, as hereinafter set forth. l

From the foregoing description, it will be obvious that after the attachingdevice 14 has been secured in proper position. upon the bottom of the ordinary heel of a shoe, h t the rubber hee may bere di y app ied thereto by positioning the ,L-shap ed slots 12 over the Lshaped flanges 15, and forcing the heel forward, during which process, the locking member 16 will ride upon the inclined surface 18 and deflect the rear portion of the heel downward so that when this looking member registers with the groove 13, said groove will be snapped over this looking member, and thereafter the rubber heel will be securely held against accidental displacement; and on account of the circular shape of the locking member, a relatively large surface is provided for sustaining the shocks incident to walking, and thus prevent chafing or the wearing away of the wall of the groove 13. This is of considerable Importance inpractice, since heavy strains and shocks are brought to bear upon the fastening device and those portions thereof which maintain the heel in position.

hen the rubber heel is in place only the thin edges of the fastening device appear flush with the inner edge of the heel, as shown in Figs. 1 and 2, and thus the appearance of the heel is not marred by the prominent display of metal upon the outer surfaces thereof.

When it is desired to remove the rubber heel, it is only necessary to spring the rear portion thereof downward suliiciently to disengage the groove 13 from the locking member 16 when the heel may be forced rearward, the slots 12 sliding along the Lshaped flanges 15.

heel is produced v'ly held against any displaceinenteither lon- Bymy improvedconstruction rubber which when in place is-firmgitudinally or sidewise, and yet is quickly and conveniently attachable or detachable since in the attaching of the heel it is guided into accurate position by the flanges 15, and the rear portion thereof is sprung downward by the riding of the locking member upon the inclined surface 18. 4

"Of course I do not wish'to'be limitedto the exact details of construction as herein-shown asthese maybe varied Within the limits of V the appendedclainis'Without departing from the spirit of thy invention; Having thus tully described my inventlon,

What I claim as new and useful is: a

Inarubber heel for'shoes, an attaching device comprising two guiding flanges and a locking flange in combination with a rubber heel having guiding grooves thereinadapted to" slide over the 'guidin'gflanges' of the atengage the locking tion of the heel 't-aching'device, a-locking groove adapted to; flange, and an inclined, surface leading fromthe inner edge of'the heel and terminating at" the locking groove,

said inclined surface serving to coact with thelocking'flange forriding the rear pordownward until said locking flange registers'with the locking groove.

2. The herein described combination of a fastening device adapteditobe securedgto the a guidingflangesand spaced to the rear thereof, said locking flange extending, substantiallygthe completedistance between the gu ding 'flan'ges, and rubber heel having, L,-,

shaped grooveswfor registration With the,

guiding flanges and also having. alocking groove inspaced relation to theL-sha-ped grooves flange and further having an inclined surface formed 'in'the inner face and extending from the forward edge of the heel to said lockinggroove. f a I In testimony whereof, I have hereunto affixed my signature. r i
